On the Hilux v6 conversions I did I used the standard v6 fly-wheel and pressure plate
with a 4x4 Hilux clutch plate.

Good v6 engines are getting sarce. See if you can find a black engine, the ones with
the black aluminium tappet covers. The have hardened valve inserts and can run on
unleaded fuel.

In the 80`s - 90`s I build a few ass kicking Essex v6 engines.
Had all the spares ready to stroke and bore a v6 3.0l to 4.0l.
Their head design robs them from power.
You still get nice aftermarket heads and stuff.
